Conocer los equipos que están conectados a mi red.

Vamos haber varias herramientas que nos permiten conocer los equipos alcanzables de nuestra red loca.

Nmap

Nmap es un programa de código abierto que sirve para efectuar rastreo de puertos escrito originalmente por Gordon Lyon (más conocido por su alias Fyodor Vaskovich). Se usa para evaluar la seguridad de sistemas informáticos, así como para descubrir servicios o servidores en una red informática.

 

rokitoh@red-orbita:~$ nmap -sP 192.168.1.1/24

Starting Nmap 5.00 ( http://nmap.org ) at 2011-08-30 14:03 CEST
Host 192.168.1.1 is up (0.00058s latency).
Host 192.168.1.102 is up (0.00025s latency).
Nmap done: 256 IP addresses (2 hosts up) scanned in 2.54 seconds

fping

Instalación para debina o derivados.

rokitoh@red-orbita:~$ apt-get install  fping

Fping es una herramienta que te permite enumerar una red en poco tiempo, y especificar en un rango de red determinadocuales son las ip que están activasdentro de ese rango.

 

rokitoh@red-orbita:~$ fping -g 192.168.1.1/24 2> /dev/null | grep alive
192.168.1.1 is alive
192.168.1.102 is alive

ip neig

Herramienta de configuración del protocolo ip.  Con ella podemos ver y modificar rutas.

rokitoh@red-orbita:~$ ip neig

Se nos abre un asistente de instalación, Adelante.

 

 

Leemos y aceptamos la licencia.

 

Le decimos donde queremos instalarlo.

 

Nos muestra un mensaje diciéndonos que la configuración ya esta insta para su instalación.

 

 

Empieza a instalar…

 

Finalizamos el asistente.

 

 

AutoScan-Network es un escáner de red que nos permite explorar y controlar los dispositivos y  equipos conectados a la misma

Cuando abrimos AutoScan nos muestra un asistente para configurar la red que queremos escanear.

 

 

El nombre de la red.

 

Localhost

 

 

La interfaz por la que vamos a hacer el scan.

 

 

Resumen de la configuración.

 

 

y empieza a escanear todos los equipos que se encuentren en la red.

 

 

 

Web oficial: http://autoscan-network.com/

 

Pues hasta aquí, espero que os haya servido y si conocéis algún otro software  o manera de como escanear los equipos que se encuentran en nuestra red ponerlo abajo.

 

Un saludo, rokitoh!
